Jonathan recalls: "The game Grand Prix Drivers was originally developed for Beyond Belief, as a conversion of a C64 game. Its original title was Jimmy's Grand Prix, and while I don't remember seeing it mentioned in a Speccy mag, it was previewed in C64 magazines.
Sadly, problems with the C64 version meant it wasn't released before Beyond Belief disappeared, and I ended up renaming it and putting it on the Bumper Boogie Pack when Your Sinclair folded."

This title was also advertised for and/or published on the Commodore 64
